[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 5In the embodiment of the utility model, the novel battery shell structure includes a shell 1, the shell 1 has an opening at one end, the open end of the shell 1 is connected to a shell cover 2, a sealing gasket 5 is arranged on the outer wall of the lower end of the shell cover 2, and two symmetrically arranged connecting components 3 are arranged between the shell 1 and the shell cover 2; the connecting component 3 includes a cylinder 301 fixedly connected to the inner wall of the shell 1, the cylinder 301 is located on one side of the open end of the shell 1, one end of the cylinder 301 is connected to a limiting ring 302, and the other end of the cylinder 301 is provided with an air hole 306, and the cylinder 301 A spring 305 is arranged inside, one end of the spring 305 is connected to the piston 304, and the other end of the spring 305 is provided with a limit block 309; the outer wall of the pull rod 303 is sleeved with a spring 305, the spring 305 is located between the piston 304 and the limit ring 302, the upper end of the limit block 309 is rotatably connected to a handle 308, both ends of the shell cover 2 are provided with a cavity groove 6, the upper end of the cavity groove is connected to a guide column 307, and the handle 308 is slidably inserted into the guide column 307; the aperture of the air hole 306 is smaller than the outer diameter of the piston 304.

[0021] In this embodiment: Since the existing battery shell structure is relatively simple, most of them are to put the battery in the shell, and then use bolts to seal the shell cover to block the open end of the shell. When repairing or recycling waste batteries, they need to be disassembled. However, after the battery has been used for a long time, the bolts used to connect the shell and the shell cover will rust, which increases the difficulty of disassembly and indirectly affects the efficiency of disassembly. Therefore, this solution can facilitate the disassembly and assembly operation between the shell 1 and the shell cover 2 by setting a connecting component 3 between the shell 1 and the shell cover 2, and at the same time improve the sealing of the connection between the shell 1 and the shell cover 2, prevent dust and humid space from entering the shell 1, and provide a good sealing environment for the battery.

[0022] Specifically, when using this solution, first install the battery into the housing 1, and then dock the housing cover 2 onto the open end of the housing 1. It should be noted that when installing the housing cover 2, the handle 308 needs to be rotated to be on the same horizontal line as the pull rod 303, and then the cavity groove 6 is aligned with the handle 308 for insertion, and the housing cover 2 can be docked onto the open end of the housing 1;

[0023] Afterwards, by pulling the handle 308, the piston 304 is raised. When the piston 304 moves upward, the air in the housing 1 can be sucked into the cylinder 301, thereby generating negative pressure in the housing 1. The housing cover 2 will be firmly adsorbed on the open end of the housing 1. Since there is a sealing gasket between the lower end of the housing cover 2 and the open end of the housing 1, the sealing between the housing 1 and the housing cover 2 can be effectively improved.

[0024] When the handle 308 is completely pulled out, the stopper 309 is pulled out, and the handle 308 is twisted to drive the stopper 309 to rotate 90 degrees, so that the two ends of the stopper 309 overlap the top surface of the guide column 307, and then the handle 308 is folded 90 degrees to achieve a quick sealing connection between the housing 1 and the housing cover 2. Conversely, the housing cover 2 can be removed from the housing 1 by reversing the above steps.

[0025] Please refer to Figure 3 and Figure 5 The cavity groove 6 opened on the shell cover 2 has the same structure as the cavity in the guide column 307, and the cross section of the cavity groove 6 is matched with the limit block 309.

[0026] In this embodiment: by pulling the handle 308, the limit block 309 can be moved up and down in the cavity 6 and the guide column 307. When the limit block 309 is rotated, the limit block 309 is not aligned with the cavity 6. At this time, the height position of the limit block 309 can be limited.

[0027] Please refer to Figure 2 , Figure 3 and Figure 5 The handle 308 is rotatably connected to the limit block 309 via a shaft; limit slots 4 are provided at both ends of the top of the guide column 307.

[0028] In this embodiment, the shaft between the handle 308 and the limit block 309 is an interference fit. After the handle 308 is rotated, the handle 308 and the limit block 309 no longer rotate relative to each other without being subjected to a large external force, which facilitates the adjustment and maintenance of the folding rotation angle of the handle 308. After the limit block 309 is pulled out of the guide column 307, when it is rotated 90 degrees, the two ends of the guide column 307 can be inserted into the limit groove 4, so that the rotation of the limit block 309 can be restricted.

[0029] Please refer to Figure 2 The pull rod 303 passes through the middle of the limiting ring 302 , and the maximum compression amount of the spring 305 is greater than the length of the handle 308 .

[0030] In this embodiment: the function of the spring 305 is to give the limit block 309 a reaction force. The compressed spring 305 will apply a reset pulling force to the limit block 309. When the two ends of the limit block 309 are in the limit groove 4, the reaction force of the spring 305 can be used to firmly confine the limit block 309 in the limit groove 4.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
